"every one of them have a fatty acid deficiency." This is the same crew that writes about the "tenants of vital health."
I wrote this outfit and asked them if they could use a copy editor: "Oh, no, thanks, we've got plenty of in-house staff." Yah, maybe, but too many of them seem to lack English skills (wouldn't be surprising in the face of the "Affirmative Action" rubbish in hiring practices).
And while we're at it, "everybody" also uses the singular verb, even though, yes, it evokes an image of all the people in the world.
